At approximately what value does the atmospheric pressure need to be in order for water to boil at 80ºC instead of 100ºC?

Water ionizes by the equation h2o(l)⇌h+(aq)+oh−(aq) the extent of the reaction is small in pure water and dilute aqueous solutions. this reaction creates the following relationship between [h+] and [oh−]: kw=[h+][oh−] keep in mind that, like all equilibrium constants, the value of kw changes with temperature.

The pressure in a fluid is affected by which characteristics of that fluid

The boiling point of liquids is very high what does it indicate
